An encyclopedia or encyclopaedia is a reference work providing summaries of information from either all branches of knowledge or from a particular field or discipline. Encyclopedias are divided into articles or entries that are often arranged alphabetically by article name and sometimes by thematic categories. Encyclopedia entries are longer and more detailed than those in most dictionaries.
Encyclopedias have existed for around 2,000 years and have evolved considerably as a valued source of reliable information compiled by experts, printed versions found a prominent place in libraries, schools and other educational institutions.
The appearance of digital and open-source versions in the 20th century has vastly expanded the accessibility, authorship, readership, and variety of encyclopedia entries and called into question the idea of what an encyclopedia is and the relevance of applying to such dynamic productions the traditional criteria for assembling and evaluating print encyclopedias.
